A hoop and a disk with uniform mass distribution have the same radius but the total masses are not known. Can they both roll down a ramp without slipping and reach the bottom in the same time? And if so, what can you deduce about the relative masses?
a) The hoop and disk have the same mass.
b) The hoop is heavier, twice the mass of the disk.
c) The disk is heavier, twice the mass of the hoop.
d) They cannot reach the bottom at the same time regardless of mass.
e) The disk is lighter, three-fourth the mass of the hoop
